Can't control knee in blender 2.92
After hours of searching google and youtube found the solution finally. For those who may face this issue:
1- Select metarig
2- go to edit mode
3- rotate thigh.L and thigh.R (90 degree in my case)
4- go back to pose mode
5- under Object Data Properties &gt; Rigify Buttons activate Advanced Options then Overwrite then click on Generate Rig
If any bone has problem for generating rig:
1- copy the bone name
2- remove it
3- create exact same bone(start and end points are important)
4- set parent
5- set children
6- set the name again
7- rigify again
Don't forget to apply transforms before any generations specially for rigify!
